How is it that we know the white color reflect all light, and the black color absorbs all of it, but darker skinned people suffer less damage from staying in the sun?

Question

Why do darker skinned people have a natural higher SPF? If a blacker color makes them more absorb more light, wouldn’t they also take more heat and sun energy? How does that make them more protected than pale people?

Answer 1

It isn’t the visible light that causes damage, so the body’s ability to reflect or absorb visible light isn’t really important.
